Pixel (pixel)
Pixel or PX is a basic unit of a computer's screen device, which is a point. All other units have a fixed proportional Conversion Relationship with pixels. When all length units are displayed on the screen, they are converted to the number of pixels first and then displayed. Therefore, there is no essential difference between relative length and absolute length in computer screens. All units are actually pixels, and the difference is only different proportions.

Original: "C#/WPF" modifies the DPI and Resolution of the imageProblem:The DPI of the image used by default in WPF is 96. If the dpi of the voxel we are using is not 96 o'clock (for example, 72), then WPF will automatically change the DPI of the image to 96, causing the actual size of the images to be loaded, width and
With the development of the display technology, the resolution of the screen is continuously upgraded, and the display of 1920x1080 resolution is becoming a general device. However, the default DPI of the Windows system remains at the DPI, which is bad for viewing text under a high-resolution monitor. I believe many of my friends have already tuned the DPI manu

Abstract:
This document describes how to obtain high-quality images using common drawing tools (MATLAB, Visio, PowerPoint, MSWord, and MSExcel. At the same time, I will briefly describe the effects of different image formats based on my previous experience.

That is, pixels. 1px indicates a physical pixel on the screen;
The unit of px is not recommended, because the actual size of the same px image may be different on different mobile phones.

The abbreviation of dot per inch is the number of dots per inch, also known as screen density. The larger the value, the clearer the screen.Supp
A recent study of WPF development, which mentions a feature of "Resolution independence", is the main feature of a desktop program that implements development that automatically scales the UI according to the DPI of the system when it is displayed on different resolutions of the computer, without causing distortion to the application.This one mentions the system dpi, which we can set in our Windows system (

For SV, both constructing test incentives and simulating parallel behavior of hardware, DPI is very convenient. The last time we introduced how to import and call the C function through "import" in SV.
In this section, we use a simple example to illustrate how C functions call SV tasks and functions.

High-DPI displays are becoming increasingly popular, and software naturally adapts to this change, as well as a recent internship with a dpi scaling issue.
